A named location in nginx is a special internal location block identified by an '@' prefix. It is defined using location @name { ... } and is used for internal redirects within the server configuration.

How do you perform an internal redirect to a named location in nginx?

You use the try_files directive or the error_page directive with a URI starting with '@'. For example, try_files $uri @fallback; redirects internally to the named location @fallback if the file is not found.
